RVA15MD + NUCLEO-C071RB

Good morning,

we are trying to program a RVA15MD + NUCLEO-C071RB display. When loading the TouchGFX Demo 4 the programming is not successful (see errors in the attachment). While with the TouchGFX Demo 8 everything loads correctly and the demo works.

Can anybody shows me a solution?Error Programming Demo4 _RVA15MD + NUCLEO-C071RB.png

This demo contains a circular slider, where can I find a similar circular slider that I can process?

Hello @TechnicalPBG2025 ,

 

The log says that the error happens during compilation and it happens because the RAM and flash are too small.
The STM32C0 family is aimed to be cost oriented, therefore, the graphical capabilities are challenged.
I'm sorry for any inconvenience, but the Demo 4 is available in Designer when selecting your board+display combo because it is the right resolution, however, it was not originally intended to run on entry-level chips.
Instead, we recently created the Dome 8 that is meant for that board+display.

 

The circular slider for the temperature is not a built in widget, instead we programmed it.
You can see how we did it in the TemperatureSlider and HomeAutomationView files :
